Through Micrometre and Secondary metabolite

Lab · Class 8–12Using a MicroscopeLabBiomolecules — Animated Chapter Film

Two common temperate zone species, Chlorociboria aeruginascens and Chlorociboria aeruginosa, can only reliably be distinguished by microscopic examination. Chlorociboria aeruginosa has larger spores (9–15 μm × 1.5–2.5 μm) and the worm-like cells of the outer surface are rough, unlike the commoner C. aeruginascens, of which the spores are 6–10 μm × 1.5–2 μm.

The hyphae and fruit bodies of most species make xylindein, a secondary metabolite that stains the substrate wood blue-green, with "green oak" being a valued commodity in woodworking. The blue-green pigmented wood is featured in Tunbridge ware.

Habit

Blue-green stain is evident year-round, with ascocarp production occurring from summer to fall.
